TESil

More than 60% of all the energy produced in the world today ends up as waste heat. One way to utilise this heat is to let hot air flow through a Thermoelectric Generator (TEG). 

Partners: TEGma, Sintef, UiO, UiA
Funding period: 2017 - 2019
Main goal: To demonstrate a TEG based on silicides with considerable lower price than todays TEG technology.

Background

A TEG-system has no moving parts, requires very little maintenance and, due to its modular design, can be fitted to almost any heat source regardless of size.

The core of a TEG is thermoelectric materials that converts a heat flow into electric current. The higher the temperature difference, the more electricity is generated. However, today's TEG technology is expensive, since TAGs are often made of rare, expensive and even toxic materials.

Important R&D-project

Our TESil project looks into using TEG to make electricity at its plants. In addition, the company have a great R&D-project for TEG. Together with TEGma, Sintef, University of Agder and University of Oslo, Elkem aims to demonstrate a TAG based on silicides. The project runs from 2017 to 2019.

Norwegian research partners Sintef and the mentioned Universities will contribute with important modelling, characterisation and measurement of the silicides to achieve the highest possible efficiency and durability.

Ambitious goals

The goal for TESil is to show that TAG based on silicides will produce electricity at a lower price than today’s TEG technology. By utilising Elkem’s knowledge and expertise in production of advanced silicon-based materials, we wish to develop new materials and advanced production processes for making thermoelectric silicides.

Elkem also want to develop the next generation thermoelectric materials based on harmless silicon mixed with other elements forms silicides. These silicides can also handle higher temperatures than many of today’s materials and will therefore convert heat to electricity more efficient.

Furthermore, Sintef, UiO and UiA will contribute with important modelling, characterisation and measurement of the silicides to achieve the highest possible efficiency and durability. 

TESil is supported by the Research Council of Norway.
